Re: Jumbospot - can't update/downgrade firmware
Yes, that sounds correct. I made it as in the pic below and simply held the connector pins at a slight angle whilst unlocking (they are not solderd in the PCB). The STLink programmer is not a serial adapter - get the correct thing, cheap enough on ebay or amazon. DSCN1481s.jpg Hope that helps Nigel ...

Re: Jumbospot - can't update/downgrade firmware
@ VA7KKW Ha, was their technical support person called 'Jennifer' ? Writing in their very best Chinglish ! Well, all you have to do is get a cheap ST-Link programmer and do as my post above if you want it unlocked, otherwise it does work fine, as delivered. The programmer I purchsed... https://www.a...

Re: Jumbospot - can't update/downgrade firmware
OK, just to complete this story, the chip on my jumbospot was indeed 'locked'. I purchased an ST-LINK v2 programmer from Amazon at 4.99 GBP (delivered within 2 days). Downloaded STM32 ST-LINK Utility (some small hoops to jump through, but I already had done this some time in the past), also availabl...

Re: Jumbospot - can't update/downgrade firmware
Well my ebay seller responded with a confirmation that the jumbospot is locked but "it is easy to unlock by software" (pic attached) !!
Yeah, right....
It does work fine but I'm haggling with them now, just for the hell of it

Re: Jumbospot - can't update/downgrade firmware
Thanks for your reply, it makes sense now. I may have an stlink programmer and if not a friend will. It probably won't be neccessary to upgrade it, but I would like it to be easy to do so, it's all part of the fun for me. The ebay advert described it as "The firmware is pre-loaded and is easily...

Jumbospot - can't update/downgrade firmware
I have just bought a Chinese jumbospot clone with OLED (board is not marked with type or version). It does work, but I want to check it upgrades before leaving feedback. In pi-star -> Expert -> SSH I use: sudo pistar-findmodem (and it returns) Detected MMDVM_HS (GPIO): /dev/ttyAMA0 (MMDVM_HS_Hat-v1....
